Tissue-box-size satellite created by Rice University students to help tackle space junk

Posted by in categories: mapping, space

Rice University students are developing a research satellite to help alleviate the space junk orbiting our planet.

The OwlSat CubeSat will collect data over the course of one year to see how extreme ultraviolet radiation, which is always emitted from the sun but becomes more intense during events such as solar flares, can alter a satellite’s path in low-Earth orbit, the area where the International Space Station resides. Better understanding a satellite’s orbit can help prevent collisions that can create space junk, said Ryan Udell, president of Rice University’s chapter of Students for the Exploration and Development of Space.

“We don’t have a fool-proof way of mapping orbits,” Udell said. “There are very good predictors out there, but we can’t fully predict it.”

Archaeologists use laser tech to reveal secrets of 100-km Maya road

Posted by in category: transportation

Archaeologists have used laser technology to map a 100-km (62-mile) Maya stone road that could have been built 1,300 years ago to help with the invasion of an isolated city in modern-day Mexico. The ancient highway is thought to have been constructed at the command of the warrior queen Lady K’awiil Ajaw, and would have been coated in white plaster.

The 26 ft (8 m)-wide road, also known as Sacbe 1 or White Road 1, stretches from the ancient city of Cobá – one of the greatest cities of the Maya world – to the distant, smaller settlement of Yaxuná, located in the Yucatan Peninsula.

Newly-published research has shed new light on the nature of Lady K’awiil Ajaw’s great road by making use of light detection and ranging, otherwise known as LiDAR technology. To take their measurements, the authors made use of an airborne LiDAR instrument, which beamed lasers at the surface as it passed over the ancient road.

L1ght raises $15 million for AI that protects children from online toxicity

Posted by in category: robotics/AI

L1gh t, a fledgling AI startup that wants to help technology companies combat online toxicity, bullying, and abuse, has raised $15 million in a seed round of funding from Mangrove Capital Partners, Tribeca Venture Partners, and Western Technology Investment.

The company’s substantial seed funding comes as tech companies are struggling to contain offensive and harmful behavior on their platforms. It’s nearly impossible to monitor massive platforms manually, which is why automation and AI are playing increasing roles in the gatekeeping process — but they still can’t detect every piece of abusive content. Moreover, technology companies have other priorities to juggle — such as making more money and growing their user base. Against this backdrop, L1ght is hoping to carve out a niche by focusing on safeguarding children.

Are We All Subjectively Immortal?

Posted by in categories: life extension, quantum physics

O.o woah!


When we’re watching an action movie, we might think that we’re watching main characters through a bunch of explosions to an improbable happy ending, but it’s just as accurate to say that we’re watching the ‘Quantum Immortality Hypothesis’ illustrated over and over again.

Cooling of a trapped ion to the quantum regime

Posted by in categories: particle physics, quantum physics

Neutral atoms and charged ions can be cooled down to extremely low temperatures (i.e., to microkelvins, 1 millionth of a degree above absolute zero) using laser techniques. At these low temperatures, the particles have often been found to behave in accordance with the laws of quantum mechanics.

Researchers have been conducting laser cooling experiments on and ions for decades now. So far, however, no study had observed mixtures of both atoms and ions at extremely low temperatures.

Researchers at the University of Amsterdam were the first to achieve this by placing an ion inside a cloud of lithium atoms pre-cooled to a few millionths of a kelvin. Their observations, published in Nature Physics, unveiled numerous effects that could have interesting implications for the development of new quantum technologies.

Physicists Foretell Quantum Computer With Single-Atom Transistor

Posted by in categories: computing, particle physics, quantum physics

Physicists at Purdue University and the University of New South Wales have built a transistor from a single atom of phosphorous precisely placed on a bed of silicon, taking another step towards the holy grail of tech research: the quantum computer.

Revealed on Sunday in the academic journal Nature Nanotechnology, the research is part of a decade-long effort at the University of New South Wales to deliver a quantum computer – a machine that would use the seemingly magical properties of very small particles to instantly perform calculations beyond the scope of today’s classical computers.
